, SANITARY EoTTLEcLosURE.

Specification of Letters Patent.

` Application led April 12, 1911. Serial No. 620,595.

To all whom, it may concern.'

Be it known that We, ALBERT D. RAY and- CHARLES N. RUSSELL, citizens of the United as a sanitary closure or cover for milk bot-A tles.

The primary object of the invention is to provide `a more sanitary closure for the mouths of milk bottles by the provision of a beaded covering or hood adapted to receive and take over the bottle beading at the mouth of the bottle thus protecting the same4 from contamination by germs, dirt, and the like.

A further object is to prevent dirt,dust, etc., which may settle on the main body or disk portion of the closure or cap from falling into the bottle when the cap is removed as now occurs with theordinary internally arranged disk closure or cap.

`With thev above mentioned and other ends in view, the invention consists in the novel construction, arrangement, and combination of parts, hereinafter described, illustrated in some of its embodiments in the accompanying drawings, and particularly pointed out in the appended claim.

Referring to the drawings, forming a part of this specification, Figure 1, is a view partly in plan and partly in section of a form of bottle closure applied to the mouth of a milk bottle. Fig. 2, a similar View of a modified form of same. Fig. 3, a similar view of a further modilication` of the form shown in Fig. 1, the beaded covering being provided with a plaited skirtl depending therefrom and) surrounded by a split retaining ring. Fig. 4, a similar modification of the form shown in Fig. 2. Fig. 5, a further Fig. 2. Fig. 9, a view of a still further modified form. lFigs. 10, 11, and 12,' are perspective views of various forms of split skirt retaining rings. Fig. 13, a further modied form of the improved bottle closure.

Similar numerals of` referencedesignate like parts throughout all of the figures of the drawings.-

The improved bottle closure comprises a main body or disk portion 1, adapted to be seated within the mouth of the`bottle 2, in th'ej "1 usual manner, said main body portion having'a peripheral lockingprojection or Patented sept. i7, 1912.

annular flange 3, adapted to rest within and engage an annular recess or groove 4, within the mouth or neck of the bottle.

The main body portion 1, is provided with a beaded hood or covering 5, adapted to re-y ceive and take over the bottle beading 2", at the mouth of the bottle, said beaded hood or covering extending upwardly and outwardly and conforming to the contour of the beading 2a, so as to protect the latter as a sanitary covering.

If desired, the hood or covering 5 may be used in connection with an ordinary disk closure/6, as illustrated in Figs. 1, and 3,0r Athe same may be formed as in integral part of Such form of closure as illustrated in Figs. 2, 4, and 8, of the drawings. In the last named form, the improved bottle closure comprises two disks of diiferent diameter concentrically arranged, the lpper or larger disk member or hood being adapted -to project over and cover the bottle beading 2, of the mouth of the bottle. In the form shown in Fig. 5, the hood or covering 5, is separately formed and secured to the central portion of the disk portion l, while in the forms shown in Figs. 3, and 4, the covering5, is extended in the form of a plaited skirt 5, adapted to surround the bottle neck and to be retained thereon by means of a split skirt retaining ring 7, of anyl suitable and convenient form, suchfor eXample,-as shown in Figs. 10,-11, and 12.

It will be observed that when the improved bottle closure is made in the forms shown in Figs. 3, 4, 6,7, and 9, that the outer depending portions of the beaded hood or covering are slightly less in diameter than the largest diameter of the bottle beading 2a,

the bottle beading and coperating with the peripheral locking projection or flange 3, on

the inner' side, in *securely maintaining the improved bottle closure in place. The improved hood" or covering also aifords a convenient means by which the improved bottle closure may be removed from the mo'th 0f the bottle.

From the foregoing description, taken in connection with the accompanying drawings, the construction, operatlon, and advantages of our invention will be readily understood. s

Having thus described some of the embodiments of our invention, what We claim and desire to secure by Letters Patent is,-

A bottle closure, consisting of a single blank of nonmetallic material comprising a disk member and an integral angular shaped bottle bead engaging and covering rim, said mouth of the bott-le and said rim membery consisting of \an upwardly projecting -in-,

Wardly inclined annular wall,` terminating in a flat horizontally extending portion and anv inwardly inclined depending portion 'forming a constricted exterior bottle bead engaging member. l,

In testimony whereof we vhave aiXed-our signatures in `presence of two witnesses.
